DAY 01
Transition to a fasting state
The body transitions to a fasting state and fat-burning mode as it begins preparation for cellular clean-up.
DAY 02
Fat burning begins
For most people, fat burning (ketosis) begins between 24–48 hours of their fast.
DAY 03
Cellular clean-up begins
Autophagy, our body’s natural cellular clean-up system, ignites after 72 hours. Fat burning continues and increases.
DAY 04
Rejuvenation in progress
Autophagy is fully activated, and cellular rejuvenation is in full effect.
DAY 05
Cellular renewal peaks
On the last day of your fast, cellular renewal is at its peak, and you may experience an increase in energy.
